I’m glad to see HTML Parser node which I suggested last time has been added. It makes scraping web pages much easier than regular expressions.

Alexa Skill Kit’s required signature verification continues to be a headache. I might be able to download a crypto library and execute it in a Raw Function node, but the missing piece is not having access to the raw webhook input. The Webhook Input node always parses the JSON input as a property tree, and does not give workflow access to the original string. Trying to stringize that property tree is unlikely to work due to possibly different property ordering.
I wish there’s an “Enable Alexa signature verification” option where I create the webhook, or in the Webhook Input node itself.
